Abstract
A display device, a method for controlling the same, and a display panel are provided, the display device includes: a transparent substrate; a plurality of electroluminescent devices arranged in an array on the substrate, a device with variable transmittance located between the electroluminescent devices and the substrate, the device with variable transmittance is configured so that a transmittance of the device with variable transmittance is switchable between a first transmittance and a second transmittance, and the first transmittance is greater than the second transmittance; and an image acquisition device on a side of the substrate away from the electroluminescent devices, in a case where the transmittance of the device with variable transmittance is switched to the first transmittance, external light irradiating the display device can pass through the device with variable transmittance and be incident on the image acquisition device.
